Seriously though, it's a bit of a weird one that bud - just out of interest, have you seen it do the same thing in Firefox?
You might've noticed the site was up and down like the proverbial drawers last night - we were working on an issue which is causing the site to have a mahoosive go-slow each evening around 9-10pm. Once that's nailed we've got some more fixes/upgrades to integrate, and the AJAX stuff which is involved with replies and quick replies is going to get some work so you should see that sorted this week. I'll post again to let you know when it should (hopefully) be sorted.
2) Image embedding should work fine - the problem may well be related to .htaccess protection on the images you're trying to embed - more and more sites are preventing their content being embedded elsewhere using .htaccess and other tricks. If you upload an image to an Album on ASN, and embed it from there, does it show?
...That one seemed to work OK (that's a file on another server I have (completely separate from ASN) and not .htaccess (or other) protected).
